[12:00:26] <azmankin> Ari points out that people should review the notes and identify areas they want to contribute to.
[12:00:52] <azmankin> Now up: Dirk Kutscher, Edge Computing summary from Chicago breakout
[12:02:24] Renzo Navas joins the room
[12:02:35] <azmankin> Dirk’s slides (with Eve Schooler) are now up.
[12:12:37] Börje Ohlman joins the room
[12:13:42] Guy Meador joins the room
[12:16:08] <azmankin> Dirk mentions a couple of possibly related topics: DIN and the ICN Fog Computing Workshop
[12:16:39] <glob> are any of the "secret handshake" auth mech proposals related to the Socialist Millionaire's Protocol / el gamal?
[12:17:06] <glob> i thought that was a pretty well-established way to do that sort of secret handshake thing, as used in OTR
[12:17:24] <azmankin> That’s a question for Carsten, rather than Dirk, and I’ll relay it after Dirk finishes up.
[12:19:20] <glob> c.f. section 4 of https://www.cypherpunks.ca/~iang/pubs/impauth.pdf
[12:21:33] Andrew Sullivan joins the room
[12:22:31] <azmankin> Asking for show of hands for contributors to an edge computing doc - if you want to participate, let chairs, Dirk, Eve know
[12:22:40] Dave Thaler joins the room
[12:22:46] <azmankin> Next talk: Mohit Sethi is up at mic presenting
[12:23:13] Börje Ohlman leaves the room
[12:23:28] <azmankin> Topic is authorizing network access for IoT devices
[12:25:11] <Dave Thaler> @glob: the point in the WISHI workshop is that there's nothign standardized, there's plenty of evidence of existing solutions.  That might be another one that makes the same point.
[12:26:23] <Dave Thaler> but there's no RFC or implementation in widely used (D)TLS implementations like openssl, etc. as far as anyone knows
[12:30:15] <azmankin> Now speaking:  Tuomas Aura - following Mohit.  Topic is EAP-NOOB
[12:41:43] <azmankin> FYI, there was a sound of crickets just now in the room - random crickets.
[12:46:10] <azmankin> Carsten has queued to ask a question at the mic
[12:47:33] Dave Thaler joins the room
[12:47:35] Dave Thaler leaves the room
[12:47:56] <glob> thanks dthaler. was just suggesting a look at that solution if it wasn't mentioned in the existing references already
[12:48:17] <Dave Thaler> it wasn't, thanks for the pointer
[12:48:19] Andrew Sullivan leaves the room
[12:49:07] <Dave Thaler> another relevant work is draft-ietf-dnssd-privacy which is not about an auth scheme, its about service discovery, but with similar constraints.
[12:49:38] <glob> i know it is implemented in the semi-widly-used libotr library. dont think many people use SMP but it's been there for years in pidgin adium etc
[12:49:55] <Dave Thaler> but I think we need a standardized TLS mechanism
[12:50:20] <azmankin> Andrew Sullivan at the mic
[12:50:57] <glob> if there was a transport-layer solution for MITM that doesn't rely on PKI, i think it would have already been standardized
[12:51:30] <Dave Thaler> not sure I believe that
[12:52:08] <glob> i'd be happy to be proven wrong
[12:52:34] <azmankin> Erik Nordmark at the mic
[12:53:13] Andrew Sullivan joins the room
[12:54:10] <azmankin> Michael Richardson at the mic
[12:56:40] <azmankin> End of agenda has been reached.

[12:57:29] <azmankin> Carsten draws attention that the group should review a nearly done draft soon, please discuss

draft-irtf-t2trg-iot-seccons-04
